Alternator swap 110 amps

maybe this one isn't as known but I picked up a 2006 Subaru outback h4 alternator. It's nearly bolt on. Your pulley has to be bored out slightly, you need a bushing/spacer for behind the pulley, a slight longer mounting bolts and you'll need to drill the alternator so our bolt fits though it.

Between a stock alternator and Lowe's you would have all the things needed for the swap.

Im sick so ill edit and add details periodically
the pic seems to big, doing this on my phone. Will figure out later. The fc guys may want to know about this option. Easier than the taurus alt swap.

lowes parts required
1 3/8 or 10mm bolt with 5 inch shank
1 3/8 or 10mm x 1" steel spacer
3 3/8 or 10 mm washers

Stock alternator parts required
1 pulley
1 bushing behind pulley
Metal insert that mount bolt runs though

Use a slide hammer to pull the metal insert from the rear mounting tab of both alternators.
Use vise to press rx7 insert I to suby alternator
remove both pulleys
Grab the bushing from behind the rx7 pulley, you'll need it
Put the bushing in the suby alt
You'll need a washer on top of the bushing
Bolt pulley on.

electrical will be forthcoming

2006 outback h4 alternator
